ABSTRACT:
An arrangement for closing and opening a film sheet cassette, particularly an X-ray film cassette, has a bottom element, and a top element provided with a projection and movable relative to the bottom element between closed and open positions. A sliding element is provided having a projection engageable with the projection of the top element in the closed position, and disengageable from the same in the open position. A spring member urges the sliding element into and retains the same in engagement with the projection of the top element in the closed position. An elastic detent element retains the sliding element when the latter is disengaged from the projection of the top element in the open position. The elastic detent element is actuated by the top element when the latter moves from the open position into the closed position, so that the sliding element ceases to be retained by the elastic detent element and is urged by the spring into the engagement of the projection of the top element.
